RPT is essentially a technology that lets us transform digital designs into 3-dimensional solid objects for production of machine parts, prototypes, models, and moulds. It builds solid objects one layer at a time, producing premium models overnight instead of taking weeks. RPT uses various processes including selective laser sintering (SLS), laminated object manufacturing (LOM), stereolithography (SL), direct shell production (DSP), fused deposition modelling (FDM), 3D Printing as well as a host of other procedures.
